Is there a way to change the Gods ? You can change the look of your Character, can you change the God aswell ?

I had no Idea about the Game and now i want to use the God for my City Limsa. I dont want to Play the rest of the Game without a way to change that sometimes. They dont Play any roll so it shouldnt be difficult to let us change them. Otherwise i must start a new Character and yes it disturbes.

Thanks
